Yes, this is exactly my configuration. All three servers are behind routers
using NAT, and having a "real" private 192.168 address.
Does anyone have an explanation, or maybe a suggestion how to stop this?
Thanks again
Terry

I've seen this sort of thing happen when the mail servers were behind
something where address translation was going on so the system's IP
address was not the same as the public facing IP address seen in the MX
records. Do you have something like that setup withese these hosts?
